Chapter 23, Problem 42PS

Interpretation Introduction

Interpretation: The structural formula of all the primary amines have molecular formula ${\text{C}}_{\text{4}}{\text{H}}_{\text{9}}{\text{NH}}_{\text{2}}$ has to be drawn.

Concept introduction:

Amines are the hydrocabons which have nitrogen $\left(\text{N}\right)$ heteroatom. The nitrogen atom is substituted by alkyl groups which can be aliphatic, aromatic or cyclic. On the basis of number of alkyl groups three types of amines are possible.

(1) Primary Amines: The nitrogen atoms is substituted by one alkyl group and two hydrogen atoms are also attached to nitrogen atom is called as primary amine. For example,

(2) Secondary Amines: The nitrogen atoms is substituted by two alkyl groups and one hydrogen atom is also attached to nitrogen atom is called as secondary amine.

(3) Tertiary Amines: The nitrogen atoms is substituted by three alkyl groups and no hydrogen atom is attached to nitrogen atom is called as tertiary amine.
